One workaround for this is to run the unit in FAN mode for a while before finally turning it off. I.e. 'COOL' -> 'FAN' for 30 minutes or so ->...

There's really no easy way to check, as the IR communication is one-way only, there's no feedback from the A/C unit, other than the 'beep' sound. I think the best...

Please read the https://github.com/ToniA/arduino-heatpumpir#how-to-contribute. If you have an Arduino and an IR receiver, you should be able to test if the receiver understands the protocol. Of course you can also...

You would somehow need to figure out which bit turns the light on. One way is to build a receiver, and compare the signals from remote against signals from library....

You would probably need to change this like of code: https://github.com/ToniA/arduino-heatpumpir/blob/279ae403af3fee9d1478a4a2f6632fa1b653c4bb/GreeHeatpumpIR.cpp#L242 Try setting it to 0x40 or 0x60. The upper 4 bits seem to control features TURBO,LIGHT,HEALTH,X-FAN.

That's a build detail of the ESPHome. I'm sorry, but I don't have any experience on it.

Thanks, this is really good stuff, I'll take a look at this over the weekend.

Would you try out this firmware? It's a minimal_IRext_ESP8266_4M1M build from this: https://github.com/ToniA/ESPEasy/tree/mitsu_msy https://1drv.ms/u/s!AsOVS72cZynsif0o6Ig2EKEtFbDZrg?e=Rcrmom

I fixed the DRY code, and published it in Github, on my branch mentioned above. As you have VS Code and PlatformIO, you could try to build this yourself. Just...

I asked above if you could build this branch yourself. Let me know if it works.
